In July 2026, as the Northern Hemisphere entered deep summer, extreme high temperatures affected many parts of Asia, leading to record-high electricity consumption for both residential and industrial use. Real-time energy price data showed that the Chinese power spot market experienced its largest fluctuation of the year, with the day-ahead spot average price in several provinces increasing by over 20% compared to June, and clearing prices reaching the upper limit during certain periods. This phenomenon is a concentrated manifestation of the supply-demand conflict during the peak summer period and a vivid reflection of the deepening marketization of the power sector.
Spot Price Surge: Significant Regional Divergence
According to power spot trading data tracked by raw material exchanges, in the fourth week of July, the day-ahead spot market average prices in major power-consuming provinces such as Shandong, Guangdong, and Zhejiang generally rose to above 0.5 RMB/kWh, an increase of about 0.1 RMB from the beginning of the month. Notably, in Guangdong, spot prices reached the upper limit of 0.60 RMB/kWh multiple times between the afternoon and evening of July 24, setting a new high for the year. In contrast, provinces with significant hydropower resources, such as Yunnan and Sichuan, maintained relatively stable spot prices in the 0.25–0.35 RMB/kWh range due to abundant water inflow.
Looking at the intraday curve, price peaks were concentrated during the evening peak period (18:00–22:00), which highly overlaps with air conditioning loads. In some provinces, the evening peak price was 6 to 8 times that of the low-peak period (03:00–06:00), further widening the peak-to-trough price gap, providing clear price signals for energy storage arbitrage and load shifting by users.
High Temperatures Combined with Economic Recovery Pushes Load Past Historical Peaks
The primary driver of this round of spot price increases was the surge in demand. In late July, multiple cities in East and South China issued high-temperature red warnings, with temperatures exceeding 40°C for several consecutive days. According to data from the National Energy Administration, the national maximum electricity load reached 1.42 billion kWh on July 29, an increase of about 8% compared to the same period last year, setting a new record. Residential air conditioning loads contributed about 45% of the increase, while electricity demand from the tertiary industry and advanced manufacturing also showed strong growth.
On the supply side, although the operating rates of thermal and nuclear power plants were high, the peak capacity remained tight due to high coal power costs and maintenance of some units. The East China region, in particular, saw its external power transmission capacity approach its limit, making local gas turbines marginal clearing units and driving up spot prices.
Deepening Power Reform: The Role of Price in the Spot Market Becomes Prominent
2026 is the second year of operation for the power spot market after its formal transition. Currently, 28 provinces nationwide are conducting long-cycle trial operations for the spot market, and provinces such as Shandong, Guangdong, and Shanxi have achieved normalized settlements. The price fluctuations in the spot market are a true reflection of the supply-demand relationship, and the era of "price suppression by administrative directives" is passing.
Industry experts point out that the rise in spot electricity prices is not a negative thing; it sends a clear signal that "electricity is a commodity." High prices incentivize the increased supply of peak resources such as thermal power and energy storage, while also curbing unnecessary consumption from some flexible loads, thereby promoting optimal resource allocation. For industrial and commercial users, this means they need to pay closer attention to short-term price trends and rationally plan their production schedules.
Insights for Energy Spot Price Observers
The energy spot price inquiry service is highly valuable at present. Whether for power retailers, large consumers, or small and medium-sized industrial and commercial operators, real-time monitoring of power spot prices allows for more precise capture of low-price periods to reduce purchasing costs. Furthermore, price fluctuations offer arbitrage opportunities, especially when combined with energy storage facilities, where charging during low-peak and discharging during peak can yield considerable returns. In the coming week, high temperatures are expected to persist due to the sustained subtropical high pressure, keeping real-time electricity prices at a high level. However, there is a risk that cooling brought by typhoons could cause a short-term price drop. Users are advised to closely monitor weather forecasts and grid supply and demand warnings to dynamically adjust their strategies.
Data Overview (Typical Day, July 24, 2026)
- Shandong: Day-ahead average price 0.52 yuan/kWh, highest price 0.60 yuan/kWh, lowest 0.20 yuan/kWh
- Guangdong: Day-ahead average price 0.58 yuan/kWh, highest price 0.60 yuan/kWh, lowest 0.28 yuan/kWh
- Zhejiang: Day-ahead average price 0.55 yuan/kWh, highest price 0.60 yuan/kWh, lowest 0.25 yuan/kWh
- Yunnan: Day-ahead average price 0.27 yuan/kWh, highest price 0.38 yuan/kWh, lowest 0.15 yuan/kWh
Overall, the real-time electricity market in the summer of 2026 demonstrates the mature characteristics of "price discovery and resource optimization." As the proportion of new energy installations continuously increases, intra-day fluctuations in electricity prices will become the norm, and the energy spot price query tool will transition from an "option" to a "necessity." Yaxianhui will continue to track the latest market trends to help you seize market opportunities.
